To calculate performance per dollar, we divided the total TPS by the total solution cost of each configuration. (For more information on how we arrived at our cost analysis results, see the science behind the report.) With RAID 10 enabled on the SATA and SAS SSDs, the Dell EMC PowerEdge R740xd server with RM5 Series SAS SSDs provided 0.1150 TPS per dollar, whereas the configuration with enterprise SATA SSDs delivered 0.0663 TPS per dollar—meaning the configuration with value SAS SSDs produced 73 percent more TPS per dollar.
CD5 Series data center NVMe SSDs increased value for money even further, delivering 109 percent more TPS per dollar than the RAID-enabled enterprise SATA SSDs we tested. Without RAID enabled on the SATA and SAS SSDs, RM5 Series value SAS SSDs and data center NVMe SSDs still delivered 33 percent and 30 percent better performance per dollar, respectively. For both of these configurations, a fully utilized CPU impacted the TPS-per- dollar metrics (as we explain in more detail on page 4). However, both the value SAS and data center NVMe SSD configurations demonstrated significant potential performance-per-dollar savings compared to the enterprise SATA drives we tested.
